A female bird, often referred to as a hen in species like chickens, plays a crucial role in reproduction. She typically lays eggs, which can be fertilized by a male bird, known as a rooster. The female's nurturing behavior includes incubating the eggs and caring for the chicks once they hatch. In many bird species, females are responsible for building nests and selecting safe locations for their young. They often exhibit different plumage compared to males, which can be more colorful or patterned to help with camouflage. This adaptation aids in protecting their offspring from predators in the wild.
